Common questions about Hennepin County building permits
How do I find which city issues my permit?
Use the Hennepin County Property Map to confirm your city — zip codes don't always match city boundaries. Each city has its own building department, portal, and requirements.
How long does a permit take in Hennepin County?
Simple permits (roofing, windows) are often approved within a few days online. Projects requiring plan review take 2–3 weeks. Submit early — spring and summer backlogs are real.
Can I apply for a permit online?
Most Hennepin County cities have online permit portals. Minneapolis uses ProjectDox. Simple permits can be fully submitted and approved online. Complex structural projects may still require in-person submission.
Does my contractor need to be licensed?
Yes. Electrical, plumbing, and HVAC contractors must hold a valid Minnesota state license. Verify any contractor at the DOLI license lookup tool. If they won't pull a permit, walk away.
Can a homeowner pull their own permit?
For some projects yes — decks, basement finishing, and similar work done by the homeowner. Trade work (electrical, plumbing, HVAC) must be pulled by a licensed contractor. Rules vary by city.
What happens if I skip a permit?
Cities can require walls to be opened or work removed for inspection at your cost. Unpermitted work must be disclosed when you sell and can kill a deal. Insurance may also deny related claims.
